i made sisyphus a fruit fly and put him oncall 🪰 🥀 In September 2026, scientists at HHMI Janelia, Cambridge and Google Research finished mapping every neuron and every connection in the brain and nerve cord of a male fruit fly: more than 166,000 neurons and around 125 million connections, traced from electron microscope images of a real fly and released for anyone to download. This fly is running on that map. Each of its neurons is simulated as a cell that builds up charge and fires, and the firing of its descending neurons, the ones that carry commands from the brain to the legs, is what drives the legs you see walking. #fruitfly #flybrain #oncall #softwareengineer #simulation
